Technical Field
The invention relates to the technical field of safety fire fighting, in particular to an outdoor water leakage self-closing fire hydrant.
Background
A fire hydrant is called fire hydrant in formal name, and is a fixed fire-fighting device which mainly has the functions of controlling combustible substances, isolating combustion-supporting substances and eliminating a fire source.
The fire hydrant is generally divided into an indoor fire hydrant and an outdoor fire hydrant, the outdoor fire hydrant mainly comprises a pipe body, a water pump and a water source, and is mainly installed on two sides of a road or a street to provide emergency water sources for fire extinguishing, but vehicles and pedestrians are numerous in downtown areas, so that the vehicles are easy to approach two sides of the road when avoiding pedestrians, when the vehicles driven on the road are out of control or are not operated properly, the fire hydrant is easy to collide, the fire hydrant is deformed under force, the position where the upper shell is connected with the lower shell is torn, the pipe body on the lower portion of the fire hydrant is broken under force, the fire hydrant cannot flow around the water source, the water source inside the fire hydrant is sprayed outwards, further, the loss of a large amount of water sources is caused, the normal use of the street is influenced, the space between the pedestrians and the vehicles is reduced, and the arrival time of maintenance personnel is further influenced, the maintenance degree of difficulty that increases the fire hydrant, and the casing buries inside the earth's surface under the fire hydrant, receives humid environment's influence, and the junction corrodes easily, appears leaking the phenomenon, further causes the water source unnecessary extravagant.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides an outdoor water leakage self-closing fire hydrant, which has the advantages of automatic closing after water leakage and automatic closing after rupture, solves the problem that the fire hydrant is easy to collide when vehicles driven on a road are out of control or the operation is not proper, so that the fire hydrant is stressed and deformed, thereby tearing the connecting position of the upper shell and the lower shell, causing the fire hydrant shell to be stressed and broken, the fire hydrant can not flow in the bound water source, causing the water source in the fire hydrant to be sprayed outwards, thereby causing the loss of a large amount of water sources, affecting the normal use of streets, reducing the space between pedestrians and vehicles, further affecting the arrival time of maintenance personnel, increasing the maintenance difficulty of the fire hydrant, and the lower casing of the fire hydrant is buried in the ground surface and is influenced by the humid environment, the joint is easy to corrode, the phenomenon of water leakage occurs, and the problem of unnecessary waste of water sources is further caused.
The invention provides the following technical scheme: the utility model provides an outdoor water leakage self-sealing type fire hydrant, includes the casing and buries in the lower casing of earth's surface, go up casing and casing through connection down, the hose is installed to the inner circle department of casing down, the top shape of hose is the arc, install the bracing piece in the hose, the outer lane department of bracing piece is provided with the retaining pipe, the outer wall of bracing piece is installed for cup jointing with the inner wall of retaining pipe, and the end of retaining pipe has seted up the inlet opening, the arc pipe is installed to the bottom of retaining pipe, is provided with the elasticity ring between per two retaining pipes, the retaining pipe constitutes the breather pipe with the elasticity ring, the top intercommunication of retaining pipe has the gasbag.
Preferably, the middle part of arc pipe inner circle is "round convex" and when atress sunken to the inboard, telescopic coil is installed to the both sides of arc pipe, telescopic coil is the cavity form and extends to the outside when aerifing, the inner circle department of arc pipe is provided with the piston piece, the piston piece is the arc when compressing, and has seted up the water conservancy diversion hole on the piston piece and be used for lining up of air.
Preferably, the shape of gasbag is the arc, gasbag initial condition is less than the play basin that the hose top was seted up, the gasbag fills the play basin that the water back was seted up at the hose top that is greater than, and the material of gasbag is elastic silica gel, the top of gasbag is connected with the aqueduct, the material of aqueduct is the silica gel hose, the top of aqueduct is equipped with the piston.
Preferably, a buffering ring positioned at the bottom of the air bag is installed in the hose, and the radian of the inner ring of the buffering ring is smaller than that of the outer ring of the telescopic coil pipe.
The invention has the following beneficial effects:
1. this outdoor self-sealing formula fire hydrant, setting through the hose, make the casing have the stereoplasm water pipe to change into stereoplasm and soft combination formula aqueduct down, make the casing fracture the back down, the hose continues to act as the effect of water conservancy diversion, reduce the velocity of flow at water source, simultaneously through the setting of arc pipe and water storage pipe, make the casing fracture the back, rivers in the arc pipe compression water storage pipe, flow to in the gasbag, make the gasbag constantly enlarge, thereby the export of shutoff hose, and then the flow of jam rivers, make the fire hydrant after the fracture automatic closure, the waste of water resource unnecessary has been solved.
2. This outdoor self-sealing formula fire hydrant, design through the piston piece, make the fire hydrant in the ruptured while, rivers receive the influence of atmospheric pressure, upwards flow in the twinkling of an eye, thereby extrude the bottom of arc pipe, make the inside air transmission of arc pipe to the expansion coil, and then increase the area of arc pipe, make the arc pipe upwards remove in the twinkling of an eye, pack the rivers in the water storage pipe to the gasbag, after casing and last casing junction leaked down, the arc pipe received the removal of rivers and moves up gradually, thereby continue to enlarge the area of gasbag, block the loss at water source.
